Rorschach was cool, but I think Malekith's face is probably pretty much as it is with some added element to make the eyes cool.

I still think this is the Stuntman not Eccleston by the way, it doesn't look enough like him in the face, but we shall see....

who makes him half dead or whatever in the comics? and what do you think will happen in the MCU? I'm assuming that is why he is "vengeful" in the synopsis, so likely Thor or Odin had something to do with it.
